Description
Technical field
The present invention relates to internal medicine the field of medical instrument technology, it is specifically related to a kind of microwave ablation that treating fibroid and controls
Treat instrument.
Background technology
Fibroid be in female sex organ in the most common type benign tumour and human body most common tumour it
One, also known as fibromyoma, fibroma uteri.Since fibroid is mainly formed by Uterine Smooth Cell hyperplasia, wherein
There is a small amount of fibrous connective tissue to exist as a kind of supporting tissue, therefore referred to as leiomyoma of uterus is more definite.Abbreviation uterus
Myomata.Most of patients is asymptomatic, is only occasionally found in pelvioscopy or ultrasonic examination.If any symptom then with myomata growing part
Position, speed, whether there is or not denaturation and that whether there is or not complication is in close relations, and it is relatively small with myomata size, number how many relationship.With more
A subserous myome person may not have symptom, and myomata can often cause irregular colporrhagia or the moon to be passed through under a smaller mucous membrane
It is more.
The clinical treatment demand of fibroid is very extensive.Operation excision myomata or uterus are still common treatment side
Method, but it is big with wound, or the shortcomings of be unable to Reservations uterus.Increasingly mature in minimally-invasive treatment technology, especially country is about double
Today that only two tires policy will open, protection uterus are of great significance.The Microwave Coagulation Therapy technology of Via vagina is in uterus
Myomata therapy field has been achieved with more successful application, but how the advantage of microwave ablation techniques to be combined still to need deeply to be ground
Study carefully.Though Microwave Coagulation Therapy fibroid has Preliminary Applications, existing microwave ablation antenna is unfavorable for Via vagina from palace
Cavity surface is treated, and is not only artificially destroyed perimetric integrality through abdomen puncture microwave ablation, is also be easy to cause neighbouring
Intestinal tube, trauma of bladder, and treatment speed is slow, and visualization is low.
The principle of micro-wave therapeutic disease is more complicated, is mainly realized by fuel factor and biological effect.Due to pole
Property it is intermolecular there are magnetic resistance to generate drag effect to oscillation, to consume microwave energy and heat, reached using these heats and controlled
The purpose of disease, here it is the fuel factors of micro-wave therapeutic.The characteristics of micro-wave therapeutic, uses high-frequency partial radiation, in smaller microwave
Under the conditions of power output, you can reach certain therapeutic effect.Microwave energy can be absorbed by tissue generation endogenous pyrogen, to human body group
The effective interaction depth knitted is 5-7CM.Microwave is efficient to the fuel factor of tissue, penetration power is strong, is produced simultaneously with inside and outside
The advantages of heat.
Domestic and international numerous studies prove, tumour cell at a temperature of 42.5-43.5 DEG C will atrophy so that death.It is micro-
After Wave heating occurs, the mode for treating tumour has two kinds：One is microwaves to enter from extracorporeal irradiation；Another kind is microwave
It is sent to patient's body direct irradiation tumour, this two kinds of therapeutic modalities can be selected according to diseased region.When microwave action is in body
When tissue, the high-frequency vibration of histocyte intermediate ion, hydrone and dipole can be caused.When microwave output energy is low, radiant heat
When can be few, local blood circulation can be enhanced, accelerate local metabolic, enhance local immunocompetence, therefore, office can be effectively improved
Portion's blood circulation promotes absorption of edema, anti-inflammatory analgetic.
Microwave Coagulation Therapy fibroid has the following advantages that：Reservations uterus does not destroy pelvic cavity physiological structure, sub after treatment
Palace myomata is inactivated and is obviously reduced until disappearing.Ovarian function is had no significant effect, of that month patient menstrual cycle is being just after treatment
Often.Without operating on, is punctured in lesion from vagina through uterus when treatment, be implanted into microwave needle.Easy to operate, rapid, effective,
Safety, wound are small.Hospital stays is short, it is only necessary to 1-2 days.
